Mosquitoes Will Be Here Sooner Than People Think

Weather in Wisconsin can be quite extreme at times and can go from one extreme to another in a very short amount of time. While some parts of the state are expecting new snowfalls this week, the truth is that spring is on its way. But with warmer weather come some pesky insects, including mosquitoes.

Pellitteri explained that “the mosquitoes that you see at the first warm-up date are the species that over-winter as adults, which are not the dominant mosquitoes. So, technically speaking, if you get a sunny 55-degree day, you can find mosquitoes outside.”

But it’s a different story for the mosquitoes that torment people throughout the summer. Those species, Pellitteri explained, “are either the snow-melt mosquitoes or the summer flood water mosquitoes. And in both cases, those are eggs right now that are kind of frozen.”

It will take a more extended warm-up and available water for them to really develop. Pellitteri said that Wisconsin usually hits that very close to Memorial Day. In a particularly warm spring, like the state had in 2012, it could be a few days early, he said, and in a particularly cool spring, it might be a few days late.
